Lift-off is scheduled for 10.54am local time (3.54pm BST) from the Kennedy Space Center in Florida on Saturday, weather permitting.
It is the tenth launch of Starlink satellites and will take the total number in orbit close to 600. SpaceX boss Elon Musk ultimately hopes to create a 12,000-strong constellation in order to beam high-speed internet back down to Earth.
The launch was initially scheduled for 26 June but was delayed by 12 days as SpaceX said its team "needed additional time for pre-launch checkouts". A second launch attempt on 8 July was scrubbed due to poor weather.
SpaceX will make a live stream of the launch available 15 minutes before launch, which will be available here. You can also follow The Independent's live blog below.
